The gap between the wealthy and the poor is most extreme in several of the United States’ most prosperous and largest cities because the rich are so very rich. But among the country’s 50 largest cities, Miami ranks No. 3 in wealth gap for the opposite reason: the poor here are so very poor.
The lowest quintile of Miami residents earned just $10,348 in 2012, according to a study released Thursday by the Brookings Institution, the Washington-based think tank. That’s about half the national average for the 50 cities studied. The top 5 percent earn $164,031 — less than any of the other 9 cities with the nation’s greatest wealth gap.
The study examined data for the City of Miami and did not include other municipalities or unincorporated areas in Miami-Dade County.
Baltimore, which ranked 10th in the study, also suffers from very low incomes. There, the lowest 20 percent earns $13,522, while the top 5 percent earn $164,995.
In the wealthier cities of Atlanta, San Francisco, Washington, New York, Chicago and Los Angeles, high wagers among top earners created massive gaps. The data suggests that many sources of both economic growth and income inequality have co-existed near each other for the past 35 years .
These wealth-divided cities may struggle in the future to provide adequate public schooling, basic municipal services because of a narrow tax base and “may fail to produce housing and neighborhoods accessible to middle-class workers and families,” the study said.
“There’s something of a relationship between economic success and inequality,” said Alan Berube, a senior fellow at Brookings. “These cities are home to some of the highest paying industries and jobs in the country.”
At the same time, Berube noted, many of these cities may inadvertently widen the gap between rich and poor because they have public housing and basic services that make them attractive to low-wage workers.
The findings come at a delicate moment for the country, still slogging through a weak recovery from the Great Recession. Much of the nation’s job growth has been concentrated in lower-wage careers. Few Americans have enjoyed pay raises. President Barack Obama is pushing for a higher minimum wage. Protesters in San Francisco have tried to block a private bus that shuttles Google employees from gentrifying neighborhoods to their offices in Silicon Valley.
Many wealthy Americans, from venture capitalist Tom Perkins to real estate billionaire Sam Zell, argue that the nation has tipped toward class warfare.
Incomes for the top 5 percent of earners in Atlanta averaged $279,827 in 2012. That’s almost 19 times more than what the bottom 20 percent of that city’s population earned, an equation that put it at the top of the list. This ratio is more than double the nationwide average for this measure of income inequality. The top 5 percent of earners across the country have incomes 9.1 times greater than the bottom quintile.
Major chasms also appeared in the tech hub of San Francisco, the financial center of New York, the seat of the federal government in Washington and the home of the entertainment industry in Los Angeles.
“In San Francisco, skyrocketing housing costs may increasingly preclude low-income residents from living in the city altogether,” the study said.
San Francisco Mayor Ed Lee said in an editorial published Thursday that “working families cannot support themselves on the (city’s) current minimum wage of $10.74 per hour” – already $3.49 above the federal minimum and 64 cents more than Obama’s proposed increase. Lee has also announced plans to build and restore 10,000 homes for low and moderate-income families by 2020.
Not all tech hubs have witnessed rising inequality.
Seattle, where Amazon and Microsoft are based, saw its income disparity decline since 2007. So did Denver. Austin, Texas, experienced a mild uptick.
“Both the tech boom and energy boom are inequality-reducing,” said Michael Mandel, chief economic strategist at the Progressive Policy Institute in Washington. “Tech introduces a path to good jobs.”
The Brookings study also found that inequality increased across cities even though incomes often fell for wealthy households between the start of the recession in 2007 and 2012.
During that five-year period, average incomes for the top 5 percent in Jacksonville, Fla., tumbled $18,999 to $152,329. But the bottom 20 percent living in Jacksonville lost a greater share of their incomes over that period, so the level of inequality increased.
Of the nation’s 50 biggest cities, just 18 experienced greater income inequality since the recession. That was due primarily to falling incomes for the poorest residents. This occurred in places that suffered from the burst of the housing bubble – such as Tucson, Ariz., and Albuquerque – and Midwestern cities still reeling from the collapse of manufacturing such as Cleveland, Indianapolis and Milwaukee.
Not all the 50 largest cities are bastions of inequality. Some Western and Sun Belt cities with smaller downtowns had a noticeably smaller divide than the national average. These cities such as Mesa, Ariz., and Arlington, Texas, are essentially “overgrown suburbs,” the study said. They tend to attract neither the highest-paying jobs nor the extreme poverty of the older cities.
